Australian Maritime College launches new tidal turbine in Tamar River

ENERGY: The Australian Maritime College boat tows a barge connected to a tidal turbine. The new project generates renewable energy.

An emerging form of renewable energy has been met with overall positive reviews from the Tamar community.

The Australian Maritime College and Sydney-based developers MAKO have come together to install and monitor a new tidal energy turbine in the Tamar estuary near Launceston.

Field experiments at a site near Reid Rock, north of the Batman Bridge, of a 2.4 metre-wide prototype have already started.

The turbine is secured beneath a floating platform and will be connected to a mooring on the east side of the estuary.

AMC project lead Irene Penesis said tidal energy was particularly exciting as it was very predictable compared with solar and wind power because of its consistent and monitorable cycles.

“Through the kinetic energy of the tidal flow, we generate mechanical power and we then convert that to electricity,” Associate Professor Penesis said.

“Because tides are extremely predictable and we can predict them two years in advance, we can predict how much power we’re going to get – when you transfer that power back into the grid you know how much you’re transferring back and you can monitor that.

“It’s absolutely essential to have the community behind these types of events because if there’s an opportunity to install tidal turbines in the Tamar River, we would want those community members to have access to that power being generated.”

Owner of the nearby Tamar River Retreat Ian Stewart said after a community meeting was held to discuss the turbines last week, there was positive interest from residents and businesses in the area.

“To use tidal power to generate electricity would be absolutely fantastic,” Mr Stewart said.

“I spend about $5000 a year on electricity because of my business, it’s probably my single biggest business expense, and if I can get that down even lower that would be great.

“I think that a lot of people in the community want to get behind this idea and want to support it.”
